Evaluation of finger skin temperature by cold provocation test for diagnosis of vibration induced white finger (VWF).
Clinical data of workers (40-69 yrs) operating chain saws for a ten-year period from 1986 to 1995 were analyzed to assess the evaluation standard of finger skin temperature for a cold provocation test (10 degrees C 10 min). Screening points of finger skin temperature for screening 191 workers with a vibration induced white finger (VWF) were obtained from receiver operating characteristic (ROC) curves. The screening points at 5 min and 10 min after a cold provocation were approximately equal to 50th percentiles of 217 workers with no symptoms (NS group). The screening points of recovery rates at 5 min and 10 min after a cold provocation almost agreed with 50th percentiles in NS group. A new evaluation standard was prepared in reference to these screening points and finger skin temperatures by fraction in NS group. The new one will be useful for the health care of workers operating vibrating tools under present working conditions.
